Split PDF Free Online — No Upload
The document is opened and edited in this tab. It stays local — a contract or a scan is never uploaded to be processed.

How it works
What a split actually produces
Every file that comes out is a whole PDF: its own catalog, its own /Pages tree, its own cross-reference table, and copies of the objects its pages depend on. That last part explains the one surprising number — the outputs added together are usually larger than the original. A font embedded once in a 40-page document has to be embedded in each split file that uses it, because a PDF cannot reference a resource in a different file. The alternative would be re-rendering pages to shed the resources, and that would cost you the text layer.
- Range syntax
- Comma-separated single pages and hyphenated ranges, 1-based: 1-3, 8, 12-20. Ranges may be listed out of order and are applied as written.
- Every-page mode
- One output file per page, named after the source with a zero-padded page number so they sort correctly in a file manager.
- Resource duplication
- Fonts and images used by a copied page are copied into each output that needs them. The parts sum to more than the whole; the text layer is what you keep in exchange.
- ZIP packaging
- More than one output is packed into a ZIP in the browser. Entries are stored rather than deflated, since PDF streams are already compressed.
How to use it
How to split a PDF online
- 01
Open the PDF
Page thumbnails are rendered locally by pdf.js so you can confirm where each section starts.
- 02
Choose ranges or every page
Type the ranges you want as separate documents, or split at every page boundary in one go.
- 03
Download the results
A single range downloads as one PDF; several arrive as a ZIP built in the tab.
Where it earns its keep
Where splitting a PDF is the job
- Sending one section of a long report to someone who has no business reading the rest.
- Separating a scanned batch of documents that came off the scanner as one file.
- Pulling each invoice out of a combined monthly statement for individual filing.
- Getting a single chapter under an upload form's file size limit.
Questions
Split PDF, answered
Why are the split files bigger than the original together?
Because shared resources stop being shared. Each output embeds the fonts and images its own pages use, so a resource that appeared once now appears several times. Only re-rendering the pages would avoid it, and that would destroy the selectable text — a worse trade.
Can it split by chapter or bookmark automatically?
No. Splitting is driven by page numbers you give it. Outline entries are not read to infer boundaries, partly because plenty of PDFs have no outline at all and plenty more have one that does not match their actual sections.
Is the file uploaded to be split?
No. The PDF is read from disk with the File API and every output is assembled in this browser tab. Nothing is transmitted, which is why there is no upload bar and no server-side queue to wait in.
Does splitting change the pages themselves?
No. Page objects are copied intact, so text stays selectable, links inside a kept range still work and vector graphics stay vector. Links that pointed at a page in a different output become dead, since their target is no longer in the document.
